Laser surface melt-hardening has recently been successfully introduced into
industry to improve the wear resistance of different parts made from gray and
A characteristics of this procedure is rapid heating of a thin
surface layer of the workpiece material above the melting point temperature.
After the completion of heat treatment, a structure-modified surface layer is
obtained consisting of the remelted and hardened layer.
Experimental results of
the study of laser surface melt-hardening process have confirmed that the
procedure is suitable also for low-power CQ^ laser sources to increase the
depth of the modified layer.
Because of remarkable repeatability of the
characteristics of the modified layer, it is possible ...
